Bootloader unlock problems?

Hello,
I bought a 64gb version throw gearbest and they installed a vendors version 7.3.14.0.0 not oficial rom. With defeats the purpose of the bootloader being locked.
I want to install the original miui 8 china or miui 8 from xiaomi.eu.
If I unlock my bootloader by submitting the request to xiaomi what I lose? What are the disavantages?
Does the fingerprint reader works on a bootloader unlocked phone with official miui 8 china?
Does it work with xiaomi.eu rom?
What are the features that cease to work with an unlocked bootloader with these two roms?
If I install xiaomi.eu rom without unlock the bootloader using Doom Slayer method I must not update by OTA or I will brick it, right?
And oficial miui 8 can I update by OTA?
Sorry for these questions but is my first xiaomi with locked bootloader and don't want to screw up by not knowing the consequences of each method?
Thanks in advance

The fingerprint will work. But Find phone will not work and it will not be secure. But your phone will be less secure like if gets stolen anybody can flash firmware and you will be loser. With find my phone nobody could even flash firmware . I have got permission within 2 days for unlocking but i have not done but i have flashed chinese firmware by using miflash. the link is here http://en.miui.com/thread-326039-1-1.html. it is very safe that way.

Security is not about flashing, is about protecting your data. Encryption makes phone more secure, not locked bootloader. We have ways to flash whatever we want with locked bootloader... how about that? Do you still fil secure?

Thank you both,
@seking for what I could understand this is the xiaomi.eu rom with even more stuff, right?
Do you have the helium version?
For that rom you just need the miflash to flash the rom via fastboot, right?
This is different from the Doom Slayer method because with it we fastboot the TWRP recovery and then use it to flash the xiaomi rom.
@nijel8, that is my question also the locked bootloader doesn't add security, gearbest flashed a custom rom even with it locked, so the security reason isn't a valid one.
Partition encrypting is only available when the bootloader is locked? If so that is one feature that is gone with unlocking.
If one unlock the bootloader can later lock it again?
With the bootloader locked we can't use miflash tool to flash fastboot rom, right? Only using EDL, and even then from what I could understand the system and data partition need to be formatted and that removes the encryption...
I just want to get rid of a rom that I don't know what is it and install a oficial rom or a rom from good sources like xiaomi.eu
After replace my rom can I update it by OTA or after I must update only by fastboot ot TWRP?
Thanks again

Bootloader status has nothing to do with encryption. Encryption always is a user option in any ROM... Not sure about MIUI though b/c they enforce encryption on both system and userdata partitions in ramdisk fstab so no user choice as far as I know. And yes... You can always lock bootloader back but will loose your data in process.
Not going to answer the second set of questions (see my signature ) not b/c I don't know but b/c never done it myself so yeah...

mi max is comparatively new phone. there are notnmany roms. development still new. therefore be careful of what you flash. for hardbrick solving we have to open the back cover which is risky. i have taken the safe mthod of not unlocking it. i flashed the rom on the locked rom with miflash via EDL. one can always flash the official rom through twrp and you will be safe.

Thanks a lot you two.
Trying to get the most information before doing something wrong.

Don't worry... Mi Max poves to be die hard phone...

Is the official bootloader unlock the only way to unlock the bootloader?

I'm attempting to flash a custom ROM on this thing for the THIRD time now. I got it last september and since then I've tried numerous times but never managed to, this is as far as I got, I managed to roll back to Lollipop and all I need to do is unlock the bootloader and install TWRP, so I can flash a new rom, but my device is "not eligible for bootloader unlock" by LG. Is it the ONLY possible way to do it? Isn't there any other way at all?

Search for TWRP in FIsH
But read it carefully. Having TWRP is not enough.

Change from Chinese rom to global rom.

Hi there I have the chance to get two of these good smartphones in China for a good price. The problem is that they have the Chinese rom on it and my parents need the italian language. Will it be possible to flash the global rom or just add the italian language?
Thanks.

Based on my experience b4 unlocking 5A, the only way you can switch from China to Global is to flash it via test point. Unless you've unlocked the phone, you could flash it via fastboot. Is your 5A unlocked yet?

Yep, that's all you need to do. After an unlock, you do have the option to relock your bootloader (which maybe you're already familiar with). The guide is on the miui forums. Good luck!

global rom flashing on China Redmi Note 5 AI?

Got a new RN5 China version yesterday. It came with 9.5.12A Chinese ROM. I'm going to flash global ROM by myself to get all Google service and debloated. Found some posts here regarding flashing global from 9.5.13. However, have 2 questions now:
1. Someone warned bricked device due to xiaomi new restrictions released recently to prevent flashing global from on Chinese version. I may not be able to flash global from on Chinese version. (Yes I knew it's Chinese version as my the other one has English characters on the box, but this one has all Chinese characters). Is it possible now?
2. Will I get ota after flashing global from if q1 is yes?

If you only needed Google application like play store and used only English, thank look into this thread about Google installer:

Thanks, but I'd like to get rid of Chinese adware as well. The existing global version of note 5 works really well and that's why I bought another one. I got this one China version to avoid waiting time. But sadly xiaomi made things more complicated now. I hope I could flash it without bricking as it's fresh arrived last night. If bricked, money throwing in the water.

Unlock bootloader and flash global stable fastboot ROM.
Yes you will get OTA update
but dont lock bootloader after flashing global ROM
and you have to wait 360 to 720 hours before unlocking the bootloader

ok, it looks like i dont need 3rd party recovery at all. just flash using the official flashing tools.
got the dame 10.0.2 updates minutes ago and auto reboot to install.
maybe i have to flash some global rom with anti4 flag on.

Yes you have to flash global ROM which has anti4 or else MiFlash throws error message saying bootloader index value is lesser than the present bootloader index value
And there won't be any chances of bricking a device if you use MiFlash

Unlock bootloader, flash twrp, flash the global zip mentioned several times in the forum. Better with EU chinese ROM as more features than global

Correct. If you try and lock the bootloader on the EU Chinese ROM or Global it's good bye phone.
If you don't unlock bootloader you'll be stuck on the Chinese ROM forever.

Why would you want to lock the bootloader?

Well what? If they want to lock the bootloader they can lock the bootloader.

That doesn't answer why! if it bricks the phone it might be useful to understand the process a bit fuller. I'm buying the Chinese version myself so want to be aware of why you'd want to lock the bootloader again

Return to stock, to sell, improve security, warranty etc
You'll only brick it if you install and lock the global ROM on a Chinese device, Chinese rom on a global device, or lock on the Chinese EU ROM

Cool. So if I get the Chinese one I'll put the EU one on.
I don't think I'd need to worry about locking the bootloader for a long time. I want this phone to last a few years and it seems reliable enough. And the processes will improve all the time.
Thanks!

Locking the bootloader is for certain applications and features that requires a more "secure" phone, since an unlocked bootloader is considered not "secure".
Payment Applications, Banking Applications, and DRM applications (Netflix) and such requires the phone to have a locked bootloader, or it will not work.

Are you forgetting Magisk? I'm unlocked since surviving 72 hours of stock locked hell. All my banking apps and Google pay have worked for the past 2 months.
BTW stock Chinese or Dev or Global are garbage compared to the EU version anyways.
